Hi I was looking on ebay and saw an orange 69 z/28 car that had 2 stickers on the core support and one on the fan shroud. I know one on the core support would be the timing sticker.Is the other a high octane fuel sticker? the one on the fan shroud looks like a sticker for the antifreeze.None of the stickers are legible from the pics.If all these are correct, what is the proper placement of them.thanks

Found the tune up sticker location for 68 in the AIM on page 20. UPC 0/B1. Shows sticker to be placed 3.5" to the left (driver side) of the center line of the car. BTW, I didn't find in the 67 AIM and I don't have a 69 AIM to reference.

In this thread regarding firewall painting, there is a picture of JohnZ's original Z. There are two stickers on the core support. Any idea what the 2 stickers are?

The one on the driver's side is the emission/tune-up sticker, and the one on the passenger side is a coolant sticker; you can also see the GM of Canada oil change recommendation sticker where the heater hoses clamp to the inner fender; the car was sold new in Canada, and has the original GM of Canada documentation.
